Light Bulbs: Overview of Different Types

Light bulb terminology can be complex. The overview of different types of light bulbs proves helpful. The key types include:

 

Type A Light Bulb

It’s the most common bulb type. Type A bulbs feature pear-shaped glass. It’s the arbitrary/standard design. They have medium or standard-sized E26/E27 screw-in bases. These bulbs are omnidirectional. They cast light in all directions. Common sizes range from A15 to A23. They are widely used as table lamps and floor lamps.

 

Type B Light Bulb

Featuring a blunt  tip and a  variety of curvatures, Type B bulbs have a standard E26/E27 base. Typical sizes range from B10 to B22. These bulbs work well in sconces, small lamps, and decorative fixtures where a rounded tip is needed. B-type bulbs are preferred for their ability to create soft, elegant lighting effects in intimate spaces.

 

Type C Light Bulb

This type resembles a candle flame. They are ideal for chandeliers and decorative fixtures. The small E12 candelabra screw base suits more ornate fixtures. While omnidirectional, the tapered top helps project light downward. Sizes span C5 to C10. Many interior designers favor C-type bulbs. It’s because of their ability to create a warm, inviting atmosphere in traditional and contemporary settings.

 

Type BR Light Bulb

BR refers to "bulged reflector". They contain an inner bulged reflective coating. It focuses light directionally rather than omnidirectionally. The curved shape also refracts light outward. With a standard E26/E27 base, BR options range from BR20 to BR40 for focused directional lighting. Their unique design makes them particularly effective in creating layered lighting schemes in residential and commercial spaces.

 

Type MR Light Bulb

Similarto BR bulbs, MR bulbs possess built-in reflective facades. These multifaceted reflector light bulbs concentrate light directionally, not omnidirectionally. The multifaceted covering ensures light shines outward to illuminate specific areas. MR16 is the most common size with a GU5.3 bi-pin base. These bulbs are particularly popular in museum lighting, art galleries, and high-end retail display environments.

 

Type PAR Light Bulb

PAR bulbs are another special among the different types of light bulbs. They utilize an internal mirrored reflector and lens. They precisely focus light like a spotlight, producing a tight directional beam. Parabolic Aluminized Reflector light bulbs range from PAR16 to PAR 64. These are extremely directional bulbs. They work for recessed cans, track lighting, and display lighting.

 

Type G Light Bulb

Type G bulbs feature a "Globe" shape that spreads light across nearly a 360° radius. With standard E26/E27 bases, G bulbs disperse ambient lighting in all directions. This makes them great for general area illumination. They are known for their soft, diffused lighting. It makes these types of bulbs perfect for creating welcoming environments in bathrooms alike.
